My name is Darius Arthur Heisenberg, but most people call me Dare. If my last name sounds familiar, it’s probably because of my great-great uncle Werner Heisenberg. He was a physicist who came up with something called the Uncertainty Principle. But listen, Uncle Werner had no idea how uncertain things really are.

I work for a group, called the Keepers, that label themselves the custodians of time. And, believe me, time is a mess. It needs all the custodians it can get. Which is, of course, why the Keepers selected me, a nineteen-year-old high school dropout, to join them. I recently worked as a janitor for a couple months. Perfect fit, right?

Okay, it didn’t make much sense to me either, but I wasn’t in a position to turn down a steady job and a roof over my head. Besides, all I’m supposed to do is travel through time and save the universe as we know it, how hard could it be?

Yeah, better hold on. This could get ugly.
